Spacer or more SAG on a Rev Dual Air

I recently purchased a Revelation RLT Dual Air to upgrade my Zesty. The fork is 150mm and my bike is designed for 140mm. The usual way would be to put a 10mm spacer inside but I wonder if it wouldn't be easier to run a little more SAG instead?
The idea would be to have the right amount of pressure in the positive chamber and a little too much on the negative so that it would eat up some travel.
Would this work or did I miss something?
Then I don't want to run the fork at 150mm with the recommended SAG since I already compensate for a too high BB with offset bushings.
Thanks in advance,
E

Running additional sag means the spring rate is wrong = bandaid. Just install a 10mm spacer and have the correct spring rate.

That would be true on a solo air fork, but the nice thing about the dual air is that you can adjust the spring rate independently from the SAG.

I have owned a few Dual Air forks as well as posted in that thread. Fork performance usually boils down to personal preference. Personally I don't tune a Dual Air fork to reduce travel. Try it for yourself and see if you like the results.
